I don't want to debate every single plot point of the show but we already saw Stannis set fire to heretics close to his house because Mel told him to. Since we were then told in all kinds of ways that Stannis had completely fallen for the Red Woman and her promises so having Stannis make the ultimate sacrifice seemed like a pretty likely outcome to me.
We are told loads of ways that completely conflict with what is shown. GRRM shows us what is happening, D&D tells us otherwise. Telling and not showing, is bad story telling :
P
Take the point where Stannis sets fire to the heretics.
This is how it is played out:
The amount of power she had over him did seem a tad excessive for someone who was from the Kings Landings court and she was clearly using him for her agenda, but they toned that down a lot and again, this scene:
Whilst Mellysnelly has more control over Stannis (power of tits apparently is unstoppable in GoT, only Renly could resist and we saw how that worked out) I find this was done in a way that eventually payed off.
Once upon a time, I found this show praiseworthy. His wife fell for the zealotry, Stannis did not, the only way we can justify Stannis burning Shireen over nothing is if we retroactively erase his character development and make him a zealot burning heretics because red woman
The point where I'd say it became obvious was this absurdly ominous scene in season 4. Selyse says she'd like to leave her Shireen at home (while emphasizing that she's a heretic) but Mel insists that she has to come along (after looking meaningfully into a fire and talking about how harsh the LoL is over dark music). I don't actually know what other interpretation there is of that scene, it seemed excessively heavy-handed to me if anything.
That and her mother despises the disfigured Shireen, believed in the cleansing of fire, hated her for being the only child she bore in a long list of failed male births e.t.c.
Immediate warning signs were that D&D actually bothered to include character development for Stannis and Shireen, where Stannis declares Shireen is the only person in the world for whom he would sacrifice everything in order to defend. GRRM likes to set up characters for victory before befalling them with tragedy, whilst D&D likes to set up characters for heartwarming moments before befalling them with tragedy.
I'm aware it contradicts his characterization in the books but it makes perfect sense given what we have seen in the show.
Thus it all contradicts his characterization in the show in exchange for shock value. The mother who despises everything about Shireen makes a massive U-turn and defends her, in defiance of all her beliefs. The father in defiance of all his beliefs and the love he bears for Shireen, sacrifices her to alleviate better conditions than he bore in the siege of Storm's End. The sacrifice proves ultimately pointless and furthers the plot in no way, going in the face of characterization.
The GRRM method is more subtle. The deaths he writes shake throughout the plot, from the more immediately affected (the Starks and Lannisters gradually losing their family members one by one) to the more distantly affected (Danaerys's character grows in confidence, as as a child she fears the Seven Kingdoms' fearsome commanders, and as an adult she hears news of Ned Stark, Tywin Lannister, Balon Greyjoy, Robert Baratheon and Stannis Baratheon get picked off one by one). This is especially pertinent in Stannis and Shireen's case, if you follow my link to the scene where Stannis burns the heretics, you will note I actually praised how the show was managing their divergence from the book's character quite solidly, with the plot advancing and much gained from the better screentime devoted to Shireen and Onion. But thrown into the D&D formula, we get touching scenes that do not advance the plot, but only serve to produce shock.
Thus we have to have contrived elements like the infamous 20GOODMEN to force Stannis into taking actions that don't make sense, actions that prove ultimately pointless and don't advance the plot.
GRRM on the other hand has been hinting that Stannis will be victorious in the battle of Ice, and in victory tragedy will befall him as he must sacrifice Shireen in victory to fulfill the Azhor Ahai prophecy and stop the Others. The greatest tragedy will be he will likely be the greatest enemy of Rh'ollor and somehow aid the Others, advancing the plot greatly to apocalyptic end game and thus finishing his arc as winter comes - instead of just 20GOODMEN and being a footnote to Brienne's arc.
Brienne of course finished her arc much too early, as brought up earlier - standing at the crossroads between avenging Renly or saving Sansa, she teleports and achieves both, spending S6 doing nothing of consequence as she's already had her cake and eat it, with no Lady Stonehearts to bring back any notion of character conflict that had long since been aborted. Everything just terminates. The only plotlines that have meaningfully advanced are Jon Snow, Cersei, Arya and Danaerys.
The great twist of Jon Snow's death was meaningless, and he somehow became KON ignoring the show's own logic. We spend 5 seasons with everyone fighting for Sansa as key to the North, only to find she is ignored, despite being the last known Stark, married to the previous Lord of the North and the Lady of Winterfell, and the one who won the battle. To reiterate, the great big twist of life and death, was meaningless.
Cersei has been characterized as having two great traits, upon which all other characterization is based:
- The lioness protects her cubs at all costs
- She amasses power and doesn't know what to do with it
To the latter end, everyone else's character arcs were aborted rather explosively, Miguel doing the best possible job with the mess he was given. Nevertheless, besides killing off her own pawns for no particular reason, nor being shown taking over the goldcloaks or the Lannister men or the Kingsguard, she manages to take power because it was awesome. Bloody hell, at least show Cersei maneuvering in some manner prior, instead of having Cersei working with the Lady of Thorns only to pull the rabbit out of the hat out of the blue. Of course, the point I'm leading up to is the lioness who protects her cub does not protect her cub and is surprisingly ok with her last child killing himself, despite having her son under the guard of the Mountain. I guess it was really important she had the Mountain rape the Septa instead of protect Tommen? Good writing D&D
Arya - fucking hell lol
Danaerys - spends six seasons trying to learn how to become a ruler, learning that she can't solve all her problems by killing her enemies and setting them on fire, ends this season learning she can solve all her problems by killing her enemies and setting them on fire. This is all whilst talking about breaking the wheel.
I do find Pr's quote on Daario to be poignant, in how Daario was accidentally written into a pretty awesome arc in the wake of Danaerys's aborted character development. Whilst all of Danaerys's problems solve themselves and she has no motivation besides freeing everyone to place themselves under the Targaryan yoke all over again, Daario spends his final season wishing to see the wondrous Empire Danaerys makes - and ends up stuck having to build it himself.
None of it makes any bloody sense. Except maybe Sir 20 of house Goodman, that is by far the best character I've ever seen in a show. Sir 20 for Iron Throne
